Surface-tension of saturated solutions of the inorganic binding in the modern foaming agent presence and its impact on the expansion and stability of the obtained foams

The suitability of the synthetic (ПБ-2000) and biological (Addiment SB3) foaming agent sand used for the foam concrete production based on Portland cement, gypsum building plaster and magnesia cements is assessed. Nonunique influence of different foaming media on the surface-tension of the foaming agents solutions, expansion and stability of the obtained foams is shown.
